Harmonic vs RampedUp: You're Probably Comparing the Wrong Tools
If you're searching Harmonic vs RampedUp, something went sideways upstream. These tools don't compete. Harmonic.ai is a startup discovery engine built for venture capital firms. RampedUp.io is a B2B contact database for sales and marketing teams. Comparing them is like comparing Crunchbase to ZoomInfo - technically both have company data, but they solve completely different problems.
Let's sort this out so you can stop wasting time on the wrong comparison.
30-Second Verdict
What Each Tool Actually Does
Harmonic.ai
Harmonic calls itself "the startup discovery engine." Its enterprise console includes 35M company records and 195M people records, with an AI agent called Scout that handles search, screening, and research. The buyer here is a VC partner, growth equity analyst, or corporate development lead evaluating early-stage companies. It's not a CRM or email finder - think research platform with API and bulk data delivery via S3, BigQuery, or Snowflake. Data comes from legal filings and public sources, with bulk data plans refreshed weekly.
Use this if you're sourcing startup deals for investment. Skip this if you need contact data for outbound sales.
RampedUp.io
RampedUp is a B2B contact database claiming up to 680M contacts, 55M company records, and 8,000 technographics. It's built for teams that need direct dials, email addresses, and social profile links for decision-makers. The platform integrates with Salesforce, and it carries a 4.7/5 on G2 across 24 reviews - users call the data "surprisingly clean given the size."
Use this if you need a large contact database for marketing campaigns. Skip this if you need high-accuracy verified emails for cold outbound, because the credit-based pricing gets expensive fast.
Side-by-Side Feature Comparison
| Category | Harmonic.ai | RampedUp.io | Best For |
|---|---|---|---|
| Database | 35M cos / 195M people | 680M contacts / 55M cos | RampedUp (raw volume) |
| Focus | Startup discovery | B2B contact data | Depends on role |
| Pricing | ~$10K-$50K+/yr | $4,500-$145,500/yr | RampedUp (lower floor) |
| Ideal User | VCs, corp dev | Sales/marketing teams | - |
| Email Accuracy | Not applicable | Not published | Neither wins here |
These two share almost nothing in terms of use case, buyer persona, or pricing structure. If you landed on this comparison, you need one or the other - not a head-to-head evaluation.
Harmonic is for VCs. RampedUp charges $0.375/contact at entry level. If you're running outbound sales, you need 98% accurate emails at $0.01 each - with a 7-day data refresh that keeps bounce rates under 4%.

Pricing Breakdown
RampedUp Pricing
RampedUp runs on annual credit-based subscriptions. One credit equals one successful API call or contact download. Here's the full tier breakdown:
| Tier | Credits/Year | Annual Cost | Cost/Credit |
|---|---|---|---|
| Entry | 12,000 | $4,500 | $0.375 |
| Team | 120,000 | $19,500 | $0.163 |
| Marketing | 480,000 | $35,100 | $0.073 |
| Agency | 1,200,000 | $49,500 | $0.041 |
| Enterprise | 3,600,000 | $91,500 | $0.025 |
| Bulk | 12,000,000 | $145,500 | $0.012 |
The first user costs $1,500, with additional seats at $500 each. At entry level, $0.375 per contact is steep for high-volume outbound. The unit economics improve at higher tiers, but you're committing $19,500+ annually to get there. For teams running lean outbound motions, that's a hard pill to swallow before you've even validated your ICP list.
Harmonic Pricing
Harmonic doesn't publish pricing - frustrating but unsurprising for a tool selling to institutional buyers. Based on comparable investor intelligence platforms, expect $10,000-$50,000+ per year depending on firm size and data access level. The enterprise console, API, and bulk data plans are all priced separately.
Here's what's annoying: Harmonic's 3.5/5 G2 rating comes from a single review. Independent evaluation is nearly impossible without getting on a sales call, which makes the opaque pricing doubly frustrating. If you're the type who wants to test before you commit, this isn't your tool.
Which One Do You Actually Need?
You're sourcing startups for investment. Harmonic is purpose-built for this. Its AI agent, company classification, and growth signal detection serve VC workflows. Nothing else here applies to you.
You need a large B2B contact database for marketing campaigns. RampedUp's volume and technographic filters make it reasonable, especially if you're already comfortable with annual contracts.
You need verified emails and direct dials for outbound sales. Neither tool is the right answer.
Look, most people searching this comparison are in that third bucket. They don't need a VC research platform or a 680M-record database - they need accurate contact data that won't torch their domain reputation. If your average deal size is under $50k, you almost certainly don't need either of these tools.
What Outbound Teams Should Use Instead
If your actual need is verified contact data for prospecting, Harmonic and RampedUp are the wrong category entirely. We've tested dozens of tools in this space, and the math consistently favors platforms built for deliverability over raw database size.
In our experience, teams running outbound at scale care far more about bounce rates and reply rates than database size. A 680M-record database means nothing if a meaningful chunk of those emails bounce. One of our customers, Snyk, dropped their bounce rate from 35-40% to under 5% after switching, and their AE-sourced pipeline jumped 180%. That's what accuracy does at scale.
The consensus on r/sales and r/coldemail tends to echo this: raw contact volume is a vanity metric. What matters is whether the email lands in an inbox and whether the phone number actually rings. HubSpot's research on email deliverability backs this up - sender reputation damage from bad data compounds fast and takes months to recover from.
Snyk's 50 AEs dropped their bounce rate from 35% to under 5% and grew AE-sourced pipeline 180%. The difference wasn't database size - it was 98% email accuracy and 125M+ verified mobile numbers with a 30% pickup rate.

At the entry tier, each contact costs ~$0.375. That's workable for light use but expensive at scale. For teams running high-volume outbound, tools with per-email pricing around $0.01 and 98% accuracy will stretch your budget 30x further.
Why doesn't Harmonic.ai publish pricing?
